Charging device for electric vehicles

1. A charging device for electric vehicles, comprising:

at least one docking station,

at least one charging unit attachable to the docking station,

wherein a plurality of recesses are provided in the docking station,

wherein the charging unit comprises a plurality of bars which are insertable into the recesses of the docking station and each of which comprises at least one first locking element

at least one locking module movable between a locking position and an open position, which comprises a plurality of second locking elements corresponding to the first locking elements

wherein, in the open position of the locking module, the bars are insertable into the recesses in such a way that the bars are movable into a snapping position, and

wherein, in the snapping position, the locking module is movable from the open position into the closed position in such a way that the bars are fixable in a form-fitting manner to the docking station by an interaction of the second locking elements with the first locking elements.

2. The charging device according to claim 1 , characterized in that

the charging unit comprises at least one tub assembly,

wherein the bars are arranged on the bottom side of the tub assembly and extend away from the interior of the tub assembly.

3. The charging device according to claim 1 , characterized in that

the locking module is formed as a locking bracket with two legs extending parallel to each other and a connecting element connecting the legs,

wherein each leg comprises at least one second locking element.

4. The charging device according to claim 1 , characterized in that

the bars comprise a pin section with a locking head as the first locking element,

wherein in the snapping position by a movement of the locking module from the open position into the locking position an engaging of the snapping head behind a recess of the locking module formed as the second locking element is carried out.

5. The charging device according to claim 1 , characterized in that

the locking module is only movable from the open position into the locking position when all of the bars are in the snapping position.

6. The charging device according to claim 1 , characterized in that

the locking module is movable from the open position to an intermediate locking position when at least one first bar is in the snapping position, and

the locking module is movable from the intermediate locking position into the locking position when at least one second bar is in the snapping position.

7. The charging device according to claim 1 , characterized in that

the locking module is fixedly integrated in the docking station, and

the docking station comprises at least one guide configured to guide the locking module during a movement between the open position and the closed position.

8. The charging device according to claim 1 , characterized in that

at least one spring element is fixed between the locking module and the docking station in such a way that in the open position a force acting in the direction of the locking position is exerted on the locking module by the spring element.

9. The charging device according to claim 1 , characterized in that

at least one fixing element is provided configured to fix the locking in the locking position in such a way that a movement of the locking module is blocked when the fixing element is fixed.

10. The charging device according to claim 1 , characterized in that

at least one sealing element is provided between the docking station and the charging unit, and

in the locking position, a seal is provided between the docking station and the charging unit.

11. A charging station, comprising:

at least one charging column with a receptacle, and

at least one charging device according to any of the preceding claims arrangeable in the receptacle.
